HOISTING TRIP AND SLING.

SPECIFICATION forming part of Letters Patent No. 617,26*?, dated January 3, 1899.

Application iilecl March 11, 1 8 9 8 To all whom it may concern:

Beit known that I, EDMUND VVILEY, .I r., a citizen of the United States, residing at Lecompte, in the parish of Rapides and State of Louisiana, have invented a new IIoisting Trip and Sling, of which the following is a specication. y

This invention relates to certain new and useful improvements in slings for elevating hay, cane, ne., having for its object to provide simple and eifective means for the purpose whereby the sling may be quickly secured around a load to be lifted and which may be released from the load with equal facility to permit it to be deposited at the desired point.

It is also an object of the invention to provide a sling which may be secured around a load after it has been placed upon a wagon, thereby obviating the necessity of employing` a separate sling for each wagon in use.

With this object in view the invention resides in the novel construction and arrangement of the parts hereinafter more particularly described.

In the accompanying drawings, forming a part of this specification, and in which like letters and numerals of reference designate corresponding parts, Figure l is a side elevation of apparatus embodying the invention. Fig. 2 is a detail view of a portion of the tripbeam and latch-frame. Fig. 3 is an end view of the apparatus, showing the parts in the positions they occupy when supporting a load; and Fig. 4L is a similar View of the parts when disconnected from a load.

Referring more particularly to the drawings, A designates a trip-beam, and B an auX- iliary beam, each of which is supported upon tie-rods 1 2, respectively, which rods preferably converge upwardly to a suitable device,

- in the present instance in the form of a ring 3, by means of which the sling is connected to any desired elevating mechanism. The tie-rods 1 2 are loosely connected with the ring 3 in order to permit their beams A B to swing laterally with respect to each other, thereby enabling them to be adjusted to planes upon opposite sides of that occupied by the ring 3. At their lower ends the tierods 1 are formed substantially T-shaped, the

Serial No. 673,537. (No model.)

lateral projection at said ends being received in separated sockets 4 at one of the lower side edges of the beam A and constituting pivotal points upon which the beam is permitted to swing.

Supported rigidly upon the tie-rods 1 at a point intermediate the ring 3 and the beam A is a beam 5, upon which is pivotally supported the upper end of a latch-bar 6, and a spring 7 is likewise connected to said beam and to the latch-bar, the tendency of said spring being to carry the said bar into engagement with the slot of a latch 8. This latch is carried upon a frame 9, connected to and extending from the beam A, and the effect of the engagement of the latch-bar 6 with the latch 8 is to prevent the beam from swinging downwardly upon its pivots. A rope or chain l() is connected to the lower end of the latch-bar, by means of which it may be drawn out of engagement with its latch when it is desired to release the trip-beam A.

Arranged at separated points along the length of the trip-beam A are pairs of angleirons 12, which extend around one side and over the top of the beams and terminate at their upper and lower ends in sockets 13 14, respectively.`

The/sc-ckets 13 are normally in planes below the lower edges of the trip-beam and below that of its pivotal points, while the sockets 14 are above the plane of said pivotal points and preferably above that of the upper edge of the trip-beam. Pivotally supported within the sockets 13 14, respectively, are hooks 15 16, and carried upon the auxiliary beam B is a series of separated hooks 17. Connected at its opposite end to the hooks 16 17 is a flexible sectional sling rope, chain, or cable C, which in the present instance is formed of two sections 1S 19, although in some instances said sling-rope may be formed of a greater number of sections, if desired, and the said sections may be of any suitable length, depending, of course, upon the diameter of the load they are to surround. At their meeting ends the sling-rope sections are adapted to be connected together and disconnected from each other, and as a simple and convenient means of effecting this the end of one secctionas, for instance, the section IOO 19--is provided with a ring 20, adapted to be engaged bya hook 21, pivotally supported at the end of the section 1S.

Means are provided for automatically releasing the sling-rope O from around the load, and while Various devices may be employed for effecting this function those which will now be described are preferred on account of their simplicity and effectiveness, the said devices being actuated by the weight of the load carried by the sling.

Connected to an arm 22 of the hook 21 is a hook-releasing line 23, which extends upwardly and is connected to the hook 15, this line being so arranged that when pulled upon it will swing the hook 21 upon its pivot and withdraw it from engagement with the ring 20, thereby disconnecting the sling-rope sections. It will be understood, of course, that a series of sling-ropes C is employed, one

sling-rope being provided -for each pair of hooks 1G 17.

With the parts thus constructed and arranged, when itis desired to lift a load (indicated by dotted lines, Fig. 8) the trip-beam A islatched in its elevated position at one side of a vertical pin passing centrally through the load, and the auxiliary beam B is arranged upon the opposite side of said line. The sling-rope sections are then passed around the sides and beneath the load and the hook 2l is secured into the ring 20. The load is then elevated and carried to the desired point by suitable means connected with the ring 3. The latch-bar 6 is then disengaged from the latch 8 by pulling upon the chain 10. This leaves the trip-beam A free to swing downwardly to the position shown in Fig. 4, to which position it is carried by the weight of the load. In moving to this position the hook 1G is lowered, slackening the tension upon the sling-rope section 1S,whi1e the hook 15 is carried upwardly, tightening the rope-section 23, which causes the hook 21 to be pulled out of engagement with the ring 20, disconnecting the sections 18 19 and allowing the load to drop out of the sling.

From the above description it will be 0bvious that a simple and effective sling is provided, capable when not in use of being folded up in a small space, and one which may be adjusted about a load while it is upon a wagon or other structure, thus possessing a great advantage over those slings which have to be placed upon the wagon before loading the same.` While I have described and shown an auxiliary beam B, it will be obvious that this may be dispensed with and the sling-rope section 19 connected directly to the tie-rods 2, or the tie-rods and beam B may both be dispensed with and the rope 19 connected directly to the ring modifications in the construction and arrangement of the parts might be made without departing from the spirit or scope of the invention, since 1. A hay-sling comprising a pivotcd tripbeam, sectional sling-ropes adapted to be secured around a load, locking devices for securing the ends of the rope-sections together, means for holding the trip-beam against movement and for releasing it to permit it to turn upon its pivot, and positive connections intermediate the trip-beam and the locking devices of the rope-sections for actuating the locking devices to disconnect said sections upon the turning of the trip-beam, substan tially as described.

2. A hay-sling comprising means for attaching it to elevating mechanism,a pivoted tripbeam connected to the attaching means, locking devices for preventing the swinging of the beam upon its pivot, means for releasing the locking devices, iiexible hay-sling ropes adapted to be secured around the load to be lifted and devices actuated from the swinging beam for releasing the sling-ropes from the load, substantially as described.

3. A hay-slin g comprising sectional locking devices, two series of flexible sling-ropes, the ends of each series of ropes being disconnected and the ends of one series carrying one section of a locking device adapted to engage with a second section of the locking device carried at the ends of the second series of sling-ropes, and automatic means dependent for their actuation upon the weight of a load for disengaging the sections of the locking devices to release the sling-ropes from the load, substantially as described.

4. A hay-slin g comprising means for attach` ing it to elevating mechanism, a pivoted tripbeam supported upon the attaching means, devices for locking the beam against and for unlocking it to permit it to swing upon its pivot, sectional, flexible sling-ropes adapted to be secured around a load to be elevated and connected at one end to the trip-beam above its pivotal points, locking devices connecting the ends of the sling-sections together, flexible lines connecting said locking devices with the trip-beam at points below the plane of its pivotal point whereby the locking devices are actuated to uncouple the sling-sections upon the swinging of the beam upon its pivot, substantially as described.
